Abstract-With the expansion of Internet and technology over the past decade, E-learning has grown exponentially day by day. Cheating in exams has been a widespread phenomenon all over the world regardless of the levels of development. Therefore, detection of traditional cheating methods may no longer be wholly successful to fully prevent cheating during examinations. Online examination is an integral and vital component of E-learning. Students' exams in E-learning are remotely submitted without any monitoring from physical proctors. As a result of being able to easily cheat during e-exams, E-learning universities depend on an examination process in which students take a face-to-face examination in a physical place allocated at the institution premises under supervised conditions, however this conflicts with the concept of distant Elearning environment. This paper will investigate the methods used by student for cheating detection in online exams, through continuous authentication and online proctors. In addition, we have implemented an E-exam management system, which is used to detect and prevent the cheating in online exams. The system used fingerprint reader authenticator and eye tribe tracker in exam session. We researched two parameters that can define the examinee status as cheating or non-cheating during exam. Through these two parameters: the total time on out screen and the number of times on out screen were computed.

Calais Again is a digital story recounting a young man, Anas’ experience of returning to France for the first time after migrating to the United Kingdom as a separated asylum-seeking child. Produced using biographical narrative and participatory arts-based research approaches, Calais Again was created as a rare self-authored contribution to Anas’ personal archive of migration documents, and as a resource for communicating the multiple and multi-layered journeys of asylum-seeking young people. In the context of COVID-19, the story additionally highlights how the pandemic is just one of many forces of ontological insecurity and constrained mobility in the lives of young forced migrants. While the project was commenced pre-pandemic, the editing and launch of the digital story took place remotely, presenting ethical, methodological and relational challenges, but also unanticipated affordances. In particular, the spectrum of options for differentiated presence enabled by online events – from anonymous observation to co-presentation – offers unique opportunities for navigating safeguarding and agency for youth researchers.

Problem statement:A simple calculation has shown what the impact of muck created during the construction of a hypothetical 50 km long and 100 m 2 cross section tunnel could be on the environment: around 8 million cubic meters would have to be discharged as waste material. One solution to such a problem could be to recycle (almost a part) the earth material, that is, the muck and debris that are excavated from the tunnel face. Approach: In order to verify the possibility of using some different breakers from the ones used in the handling plant on the studied tunnel-access, some tests were performed in the DITAG laboratory at the Politecnico DI Torino. Results and Conclusion: Different cut dimensions were considered in the recycling of the muck material from the tunnel excavation using TBMs. The obtained material, mixed with natural sands and gravels according to various hypotheses, corresponds to the dimensional requirements for the shotcrete and concrete aggregates. The optimal solution should be the mixture of the best fines produced by TBM, the products of the broken rock and some percentage of natural sands and gravels. The final choice will depend on economic factors and obviously also on the particular features in the work sites.

: Recent rice cultivars in Indonesia have more than 2000 ancestors in the pedigree, and shows a very complicated pedigree. IRRI cultivars accounted for the largest part of the genetic background of the Indonesian cultivars. Five ancestors (Dee-geo-woo-gen, Cina, Latisail, Gampai, Tadukan) contributed, collectively, 46 . 1% of the gene pool. The Indonesian rice field having the genetic background of IR64, which was estimated from the acerage of cultivars grown in Indonesia and the kinship to IR64, was 50 . 6% of the total rice field. By cluster analysis using coefficients of parentage, the Indonesian cultivars were divided into 5 groups. Cisadane and Ciapus could be used as cross parents for higher yield. The IR8 group had a light grain weight, and was not a promising cross parent for high yield. Combining ability of IR8 might be different from other cultivars. The Sintanur group had a good aroma, and the Kalimas group had a poor eating quality.
